(this is the second pants thread I have started today. I shall get a reputation as a wierd pants troll. Which I am not. Honest. )
I want to buy pretty pants, but the only pants that work under my clothes are black, white or nude plain boy shorts. My pants drawer is very dull. I went out to buy nice pants today but much as I would quite like kitch aqua y-fronts, and frilly frou frou pants, and lacey scraps, the reality is that they would get shoved to the back of the drawer while I wore my practical cotton no-frills pants.
(I have the same problem with bras - frills and bows would be lovely but practically you just need a seamless underwire in a useful colour under your clothes.)
